[O] org-indent-mode and erratic checkbox behavior?

[ardumont]

Hello,

I have a minor visual annoyance with checkboxes and `org-indent-mode`.
As I move to next/previous line, headlines stay still (ok) but checkbox keeps 
going forward and backward (2 blank spaces).
(I did not change the default binding C-n/C-p which are still bind to the 
default next-line/previous-line.)

I assume (but I can be wrong, thus feel free to correct me):
- it's not correct behavior because it does not do it to every checkbox (I am 
unable to understand the reasons it does for some and not for others)
- it's org-indent minor-mode which does this because when deactivated,
this behavior disappears

An example can be worth more than trying to explain so I'll do my best to 
describe what I see (I'll use '|' as the caret) :

- On header first character:
#+begin_src org
| IN-PROGRESS 0.5.6 [0%]
  - [ ] backlog
#+end_src

- C-n - move to the next line in the first character indented in the list
#+begin_src org
* IN-PROGRESS 0.5.6 [0%]
  | [ ] backlog
#+end_src

- C-n - move to the next line and here the first line `loses` its indentation
#+begin_src org
* IN-PROGRESS 0.5.6 [0%]
- [ ] backlog
  | [ ] Update version
  - [ ] Fix behavior orgtrello-buffer/goto-end-of-line! When going to end of 
line in checkbox, we need to do it twice, fix.
#+end_src

- C-n - move to the next line and here the first previous `loses` its 
indentation too
#+begin_src org
* IN-PROGRESS 0.5.6 [0%]
- [ ] backlog
- [ ] Update version
  | [ ] Fix behavior orgtrello-buffer/goto-end-of-line! When going to end of 
line in checkbox, we need to do it twice, fix.
#+end_src

- C-p - move to the previous line, the indentation does not change
#+begin_src org
* IN-PROGRESS 0.5.6 [0%]
- [ ] backlog
| [ ] Update version
  - [ ] Fix behavior orgtrello-buffer/goto-end-of-line! When going to end of 
line in checkbox, we need to do it twice, fix.
#+end_src

- C-p - move to the previous line, the indentation does not change but the 
indentation from the line I came from gets back
#+begin_src org
* IN-PROGRESS 0.5.6 [0%]
| [ ] backlog
  - [ ] Update version
  - [ ] Fix behavior orgtrello-buffer/goto-end-of-line! When going to end of 
line in checkbox, we need to do it twice, fix.
#+end_src

- C-p - move to the previous line, the indentation does not change
#+begin_src org
| IN-PROGRESS 0.5.6 [0%]
  - [ ] backlog
  - [ ] Update version
  - [ ] Fix behavior orgtrello-buffer/goto-end-of-line! When going to end of 
line in checkbox, we need to do it twice, fix.
#+end_src

*Note*
- source of the org file: 
https://github.com/ardumont/org-trello/blob/0.5.6/TODO.org
- The same behavior is seen if the caret is elsewhere than the first character, 
only the position changes but the behavior stays.
- org-indent-mode is cool, I'd like to keep it since I like the heading display 
rendering.
